Paper Abstract

Diffraction-limited images, of resolution many times finer than what is ordinarily obtainable through large earth-bound telescopes, can be obtained by first measuring the modulus of the Fourier transform of an object by the method of Labeyrie's stellar speckle interferometry, and then reconstructing the object by an iterative method. Before reconstruction is performed, it is first necessary to compensate for weighting functions and noise in order to arrive at a good estimate of the object's Fourier modulus. A simple al-ternative to Worden's method of compensation for the MTF of the speckle process is described. Experimental reconstruction results are shown for the binary star system SAO 94163.
